I think you bring up a fine point. Most applications have encryption built in and transparent to the user. While technical IT people in charge of infrastructure will not make this assumption, it is not unreasonable, at the same time, for small business / individual users, to not understand or know of this limitation.

VNC does not, for example, and you need to set up port forwarding through ssh. X2Go does....but I don't trust it terribly. So, RustDesk..what do you need to wrap it in? ssh?

I really want a better solution that VNC/X2Go..especially since I use hardware accelerated apps that need to use VGL to operate correctly (but underwhich operation is quite buggy).
